I have some EC2 instances that are really critical to our operations, and I'm worried about the risk of them being maliciously terminated. I'm looking for ways to protect these instances from being deleted without just relying on user mistakes. Specifically, is there a way to set up a system where we would need multiple accounts or approvals to terminate these instances? Also, what can I do to ensure that certain EC2s are automatically backed up on a daily basis? Thanks for any help!

You can enable termination protection for your crucial EC2 instances so that they can't be deleted accidentally. For backups, AWS Backup is a solid choice—it can automatically back up your instances daily. Just make sure you're familiar with using the AWS documentation for all the details.
A good approach is to manage EC2 deletions through a CI/CD pipeline. This way, no one can delete instances directly. Instead, a merge request must be created, reviewed, and approved to allow deletion. It’s a safe barrier against both mistakes and malicious intents.
To set up termination protection, use the command `aws ec2 modify-instance-attribute --instance-id --disable-api-termination`. Combine this with AWS Backup for automatic daily backups to cover your bases.
Check into Service Control Policies (SCP) if your account belongs to an AWS Organization. SCPs can deny the ability to terminate EC2 instances, giving you that extra level of protection.
Implement least privilege IAM roles based on how you're accessing accounts. Also, using MFA Delete for your backups in S3 ensures that they are safe. You can also make sure certain critical instances have termination protection enabled.
